To efficiently decrease a lead content in cement without affecting the quality of the cement.
The lead-collecting apparatus comprises: a chlorination-volatilizing furnace 2 which is installed adjacent to a cement-firing facility, and chlorinates and volatilizes lead contained in a charged lead-containing raw material (M) and the like; and a lead-collecting means 3 for collecting the lead from an exhaust gas of the furnace 2. The method for efficiently collecting lead from a cement production process includes: making the chlorination-volatilizing furnace 2 volatilize the lead in the lead-containing cement raw material (M) by using chlorine contained in a chlorination source (C); and making the lead-collecting means 3 collect the volatilized lead. The lead-collecting means 3 may have a dust-collecting means for collecting dust in the exhaust gas of the chlorination-volatilizing furnace 2. A heat source for the chlorination-volatilizing furnace 2 may be supplied by extracting the exhaust gas of the cement-firing facility from the cement-firing facility and introducing the gas into the chlorination-volatilizing furnace 2, or by sending one part of a raw material discharged from a cyclone 12 in the lowest stage of a pre-heater to a chlorination-volatilizing furnace 42. Burnt ash of municipal waste can be effectively used as a chlorination source (C) for the chlorination-volatilizing furnaces 2 and 42.
